Amanda Jaccobi
Based in Chicago, Amanda is passionate about fitness and pushing her limits. What started with strength training has evolved into a focus on hybrid performance, fueled by a growing passion for HYROX and endurance competition. Her mindset is consistency, and coming better than she was yesterday. She believes results come from showing up, putting in the work, and staying committed long after the motivation fades. Driven by conscious self-improvement, Amanda is always looking for ways to grow stronger - both physically & mentally. She believes the habits build through fitness carry into every aspect of life. Outside of training, Amanda enjoys spending time with friends and maintaining a balanced lifestyle. She loves baking, especially birthday cakes for friends, and unwinding with a good book. While fitness is a major part of her life, she believes that the strongest version of yourself is the one that works hard, has fun, and enjoys the process along the way.
